WILLIAM LAAKSO, OF SAN FRANCISCO, CALIFORNIA.

DRAWER-GUIDE.-

SPECIFICATION fornning part of Letters Patent lil'o. 763,492, dated June 28, 1904;

' 7 Application filed February 8, 190:1. Serial No. 192,712. (No model.)

To all whom may concern:

Be it known that I, WILLIAM LAAKSO, a citizen of Finland, residing at San Francisco, in

' the county of San Francisco and State of Califurniture.

fornia, have invented certain new and useful Improvements in Drawer-Guides; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

My present invention relates to improvements in drawer-guides; and it has for its objects to produce a guide which will possess the requisites of strengthand durability and which will be especially simple in construction and eflicient in operation. r

In carrying out my invention I have paid particular attention to structural simplicity and economy and in adapting the invention to use on various forms and styles of sliding drawers.

By the employment of my invention the drawer is guided in its movement and prevented from jamming or binding, while the guides and supports that are employed in the construction of my invention take the place of those usually incorporated in this class of To the attainment of the foregoing and other useful ends my invention consists in matters hereinafter set forth.

I am enabled to accomplish the above results by the means illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the outer casing of the drawer, the latter having been removed to show the guides and supports that I employ. Fig. 2 isa perspective view of the drawer proper, a portion having been broken away to show the male portion of the guide. Fig. 3 is a transverse section of the drawer and drawer-frame and the several parts of my invention. Fig. 4 is an enlarged detailed view of the bracket employed to support the lower guide. Fig. 5 is a perspective view of a portion of the guide which is secured to the bottom of the drawer. Fig.5 is aportion of a vertical section of the drawer, taken in the direction of the arrow in Fig. 2. Fig. 7 is a perspective view of the bracket employed to support the lower guide.

the U-shaped guides 4: 4:.

Referring now to the .above views by numerals, 1 1 represent two L-shaped guides which bears a revoluble wheel 3.

Directly beneath the L-shaped guides 1 1 are the U-shaped guides 4 4', on the under surface of the upper leg of each of which is formed a groove or roadway which receives the periphery of the wheel 3.

Mounted on the lowerleg of each U-shaped guide 1 4 and at the front extremity thereof is a secondary wheel 5, which engages with a corresponding groove formed on the edge of the projecting leg of each of the L-shaped guides 1 1'. These guides 4 4: are fastened at their forward extremities to the drawer-frame, while their opposite ends dovetail into a bracket 6, which is screwed to the back portion of the drawer-frame. In case it is not convenient to mount the bracket 6 inv the position shown in Fig. 1 relative to the drawerframe Ihave provided a secondary dovetailedbleato receive and secure the U-shaped guides.

Now from the above description it will be readily seen that any lateral motion of the drawer within its casing is absolutely impossible, owing to the engagement of the guidewheels in their respective guides. It is further manifest that as the drawer is first started from its casing the weight in the forward portion thereof is supported by the lower guidewheels 5, while therear guide-wheels 3 bear against the upper surfaceof the lower legs of As the drawer is drawn further open until the outer portion overbalances the inner portion the periphery of the wheels 3 will leave the lower leg of the guides 4 4 and snugly engage the roadway in the upper legs thereof.

or shrinking of the material forming the bottom of the drawer, I have formed the holes through which the binding-screws pass in securing the guides 1 1 oblong, as shown in Fig. 5.

As a means of relieving the front member of the drawer from a sudden jar as the drawer is closed I have provided the soft yielding plate 7 which strikes against the forward end of the lower guides; A.

I am aware that various changes in the form and proportion of parts of the devices herein shown and described as an embodiment of my invention can be made without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall within the scope of my invention.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, vis

1. A device of the class described, consisting of a sliding drawer, a stationary frame, into which said drawer is adapted to slide, parallel guides secured to the bottom of said drawer, secondary parallel guides held by said frame, a roller-wheel mounted on each of. said former guides, and guided in said secondary guides, and a secondary wheel in each of said secondary guides and guided in said former guides for the purpose set forth.

2. A device of the class described, consisting of a sliding drawer, a stationary frame into which said drawer is adapted to slide, parallel guides secured to the bottom of said drawer, secondary parallel guides held by said frame, wheels mounted in both of said guides and arranged for engagement with the opposite guides, and a bracket secured to said frame and provided with a plurality of dovetailed grooves into which said secondary guides are adapted to engage, substantially as and for the purpose set forth.

3. A device of the class described, consisting of a sliding drawer, a stationary frame into which said drawer is adapted to slide, parallel. guides secured to the bottom of said drawer, a wheel mounted on each of said guides, secondary parallel guides held by said frame, a wheel mounted in each of said secondary guides, said former wheels being arranged to engage with the under and the upper surfaces of portions of said secondary guides, said secondary wheels being arranged to engage with grooves in said guides on said drawer, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

WVILLIAM LAAKSO.
